HARRISON D. MGFADDIN, OF EAST ORANGE, NEW JERSEY.

THERAPEUTIC DEVICE.

Application filed February 15. 1919.

To (ZZZ am it may concern Be it known that I, HARRISON D. MGF AD em, acitizen of the United States, residing in East Orange, county of Essexand State of New Jersey, have invented a certain new and usefulTherapeutic Device, of which the following is 'a specification.

This invention is a therapeutic device and forms an improvement on thelamp of my prior Patent No. 1,267,882, patented May 28, 1918, for handlamp for therapeutic purposes. Therapeutic lamps have long been used inthe medical profession for subcutaneous treatment of the body, intendantmore particularly, for the infusion of heat to accelerate bloodcirculation, as well as the destroying of germs by ex osing them tocombined light and heat. n my prior patent referred to, a hand lamp fortherapeutic uses is described and shown and for general employmentoperates with high efficiency, particularly in the paralleling of thelight rays emanating from the lamp, so that the infra-red rays of lightare undistorted and retain their full penetrating power. Exhaustiveexperimentation, as well as successful application has proven, beyondthe slightest doubt, that the infra-red rays are the most predominantheat rays of the spectrum of incandescent carbon, and that if the raysof light are paralleled, the greatest penetrating power of these rays isassured. If the rays from any one source of light are focused, thepenetrating qualities are interfered with through distortion of therays, and in my prior patent is shown a construction which will bringabout the paralleling of the rays, as well as their projection to thepoint of application without focus.

As stated, the prior construction operates with great efficiency, but isintended for more or less local treatment, and its radius of operationon the human system is more or less limited in certain particulars. Forexample, if the treatment required is of a small local nature, such asthe knee or hand of the patient, the hand lamp will prove entirelysatisfactory, but if the entire leg or arm of the patient is affected,manifestly, the scope of the lamp is insufficient to allow of thetreatment of the entire member at one time, since, the movement of thelamp to cover the zone of operations will be required. If a single lampwere made which would opcrate over a relatively large space, the powerSerial No. 277,207.

required would be considerably greater and unless care were taken theatient might be to provide a therapeutic device which will embody allthe highly advantageous features ascribed to In prior hand lamp, butwhich will possess, in addition thereto, many additional meritoriousconsiderations. The device of the present invention is not limited tothe application of heat to a relatively small area, but is of such aflexible nature that the area of application of the light may varywithin wide extremes, so that a relatively large area may be treated aswell as a relatively small one. Moreover, provision is made whereby theentire heat and light generated may be concentrated upon a small areawith varying degrees of intensity, so that the various needs of thepatient may be served through the rendering of a very strong andpenetrating light, or by a lesser light, depending upon conditions.

Speaking generally, the invention embodies a cluster of lamps flexiblymounted relative to one another on a common support, and each of whichis electrically energized independent of the others. The lamps areadapted for individual manipulation to direct their rays on the part ofthe anatomy to be treated, and the mounting is such that the light fromall the lamps may be concentrated on a common spot to subject the partto the aggregate light and heat effect of all of said lamps, or saidlamps may be further manipulated to spread out their light and heat overa relatively large area. In either instance one or more of the lamps maybe operated through the exclusion of the others to vary the aggregateheat and light output, or they may be all used together to give themaximum intensity. By the present invention corrected concentration ofthe' Features of the invention other than those specified will beapparent from the hereinafter detailed description taken in conjunctionwith the accompanying drawings. a

In the accompanying drawings I have illustrated one practical embodimentof the invention, but the construction therein shown is to be understoodas illustrative only, and not as defining the limits of the invention.

Figure 1 is a side elevation of a therapeutic device embodying thepresent invention, all the lamps of which occupy positions to shed theirlight and heat over a1triangular shaped area lying substantially in ahorizontal plane;

Figure 2 shows a different arrangement of lamps so that the area oflight and heat rays is elongated in shape;

*igure 3 shows the lamps in such positions as to concentrate the raysfrom all of the lamps on a single point in a horizontal plane; and

Figure 4.- shows the manner in which the lamps may be shifted to throwlight and heat on a vertical plane.

Referring to the drawings, A, A and A indicate a plurality of lamps,each of which is formed and constructed after the general mannerdescribed and claimed in my prior application aforesaid in that eachlamp is adapted to project parallel rays to accomplish maximumpenetration by the infrared rays.

Each lamp is provided with a stem a, which is pivotally mounted on alink B, the other end of which is in turn pivotally fixed to anornamental shell C. The pivotal connections between the stems a andlinks B are provided with clamping bolts and wing nuts (1,, whilesimilar clamping bolts and wing nuts 6 are associated with the pivotedconnections between the links B and the ornamental shell C.

The shell C has a pivotal connection which can be locked by wing nut c,with a supporting arm D which is slidably mounted in a collar e, mountedon a standard E. A set screw (1 serves to lock the supporting arm Dagainst sliding movement in the collar e. The arm D has pivotaladjustment with the standard E, but may be locked in the desiredposition of adjustment by thumb screw 6. Current is led to the lampsthrough a cable F which passes through the supporting arm D and throughthe shell C tothe various lamps.

The standard E is of telescoping character to allow of adjustment forheight, and is provided with a hand wheel G for looking it in anypredetermined elevation. It is provided with a suitable base, not shown,and is adapted to be supported thereby in upstanding position.

The mode of operation of the device is as follows. .It will be apparentthat the device of this invention is extremely flexible in adjustments,in that each lamp of the cluster is capable of two adjustments on theshell C.

The shell C is pivotally adjustable on the supporting arm; the arm isadjustable longitudinally and pivotally on the standard and thestandard'isadjustable as to height. This allows of the projection of thelight rays in practically any direction, as well the distribution of theprojecting rays over a larger or smaller area as may be required. Thus,in Figure 1, the adjustment of the device is shown so as to project therays of each light individually down upon a hori' zontal surface, suchfor example, as a table top, the beams of light fromv the respectivelamps not overlapping one another, but said lamps projecting said raysindependently down upon the surface, so that the aggregate light of allof the lamps covers a substantially triangular area of said surface.Such an arrangement would be highly beneficial in the treatment of acrooked arm or leg where a wide range of illumination and heat were reuired.

n Figure 2, the adjustment of the standard, supporting arm and shell issubstantially the same as that shown in Figure l, but the lamps aretilted into a different adjustment so that the projected rays are inalinement on the table top to give a long, relatively narrow area oflight and heat so that an arm or leg stretched out straight on saidsurface may be treated for its entire length.

The projected lights of the lamps are shown as overlapping one anotherslightly, but the linear dimensions might well be increased by tiltingthe lamps A, A and A into slightly diverging positions to lengthen thelight or heat area on a surface on which it is projected. However, saidlamps A and A may be adjusted to bring the beam of one into convergencewith the beam of the other, and simultaneously into the beam of lamp A,after the manner shown in Figure 3, so that the light of all of thelamps will be shed upon a common point after the manner shown in Figure3. At this common point, will be the aggregate light and heat of all thelamps, and a maximum illuminating and heating power of the device issecured. If it is found that the aggregate of all the lamps produce toogreat a heat for the patient, one or two of the lamps may beextinguished, depending upon the quantity of heat required for thetreatment, and thus the intensity of heat and light from the device maybe regulated.

It has been shown how the device may be manipulated to treat portions ofthe body which may readily be placed in a substantially horizontalposition, or in the position of rest, while lying on or being supportedby a horizontal surface, but the device is also adapted to project lightand heat upon substantially vertical surfaces, through the projectedemployment of the adjustments allowed by the manipulation of the thumbscrew 0, or through such adjustments combined with additionalmanipulations of the set screw d, and the thumb screw 6', which allow ofthe tilting and extension of the supporting arm D. Thus the parts of thedevice may assume the positions shown in Figure 4, wherein the rays ofall the lamps are projecting in a substantially horizontal path. Whilethe arm I) and shell C remain in this position, the lamps may beindependently manipulated to vary the area of application ashereinhet'ore described.

While I have shown and described various positions which the constituentparts of the device may assume, it will be understood that these variousparts are shown for purposes of illustration and do not show the limitof flexibility of the device. The adjustments of the device are suchthat light may be thrown in practically every direction and frompractically every angle, depending upon the circumstances and theportion of the anatomy which requires the therapeutic treatment. Notonly is the cluster of lamps bodily moved within wide limits, but eachlamp is individually adjustable to vary the projection of light and heatto a nicety for the purpose of obtaining the desired intensity. as wellas the proper area of the projecting rays.

The present invention thus provides a device embodying all the highlyadvantageous features of parallel projection of light rays from a lampof the character shown in my prior application, and in addition thereto,provides for the varying of intensity of said light and heat, as well asthe area of application, If a small area is to be treated, and but alittle light and heat required, but a single lamp may be employed, whilewith the necessity for greater heat and light or greater area ofapplication, additional lamps may be switched on.

Having thus fully described the invention, what I claim as new, anddesire to secure by Letters Patent is:
